Job at Fin Sector

I am now really getting the hang of the job after 1 year. However, I am really furious at the newer colleagues they don't take initiatives to do things, have to tell them what to do... Yesterday, one of them, Janice was using her phone although we were rushing entries for month end. So I told her we're rushing to input entries, after a while she still use...so I ask her whether she finished entries le. She didn't say anything but later finish le. Anw after which I see her using phone again so I ask her to clarify an invoice with IT. She buay song, she says what she knows how to ask, I say ask so that u can enter the invoice journal entry. She then says “要求多多” or smth along tt line and plus a bad word then go washroom. After which we didn't speak again. Anyway I really angry at her so today I entered the entries all by myself... except for 3 payment vouchers which were passed to her... anyway I dun think I was in the wrong... but really tired of her poor attitude towards work...
